Description

Didinium intiates capture of Paramecium. Believe-it-or-not, this Didinium may accomplish the ingestion of the Paramecium in less than one minute. See other images in the link below. Also showing metachronous waves of cilia in the two characteristic ciliary girdles of Didinium nasutum. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnification is 425X. Further details are available at Wessenberg, H. and Antipa, G. 1970. Capture and ingestion of Paramecium by Didinium nasutum. J. Protozool. 17:250-270.
